LEO A. .CI-IMARA AND ANASTASI'US A. CHMARA, OF BAY CITY, MICHIGAN.

RAIL-JOINT.

To all whom it may concern:

Be it known that we, LEO A. OHMARA and .eimisrasins A. CHMARA, citizensof the United States, residing at Bay City, in the county of Bay andState of Michigan, have invented new and useful Improvements inRail-Joints, of which the following is a specification.

Our invention relates to rail joints.

One object of our invention is to provide effective means to join orcontinuously connect complementary rails without the use of bolts or theequivalent fastening means.

A other object of the invention is to provide the means stated of suchnature that a separate connecting member having means to interlock withthe rail sections will be employed.

Further objects of the invention are to generally improve theconstruction of a joint of this kind.

The invention resides in the details of construction and combinationsand novel arrangements of parts as shown in the drawings accompanyingthis application and hereinafter described.

In said drawings :-Figure 1 is a plan view illustrating the connectingmeans with complementary rails, the rails shown but fragmentarily. Fig.2 is an elevation of the same parts. Fig. 3 is a cross sectional view ofthe line 3-3 of Fig. 1. Fig. t is a View partly in elevation and partlyin section of a part of one of the rails'constructed in accordance withour invention. Fig. 5 is an elevation of the connecting member employed.Fig. 6 is an end elevation of said connecting member, and Fig. 7 is anend view of one of the rails.

In the drawings, like reference characters designate like or similarparts throughout the views thereof.

Referring specifically to the drawings, A generally designates trackrails and B generally designates the connecting member employed. j

The rails at their ends are so formed as to provide a centrallongitudinal recess 2 and ribs 3, one on each side thereof. Into saidrecess 2 project and terminate short of its base, suitable teethdesignated a which are preferably provided with an inclined face or wall5 011 one side thereof. The rail at the base flange is preferably cutaway as at 6, for a purpose that will hereinafter appear. It will benoted that the teeth 4: do

not extend the full length of the recess, but terminate short of theends of the rails so that a bearing face or surface 7 is provided. Theribs 3 at their base are preferably in clined as at 8. The rails at theends are preferably somewhat enlarged.

The connecting member B is provided with a base web or plate 9 and witha rib 10 which rises centrally and vertically therefrom. Said rib 10 isprovided with a plurality of teeth 11 which may have an inclined faceorwall 12 similar to the walls 5 of the teeth 4;. Centrally of thelength of rib 10, the same is provided with a flat bearing surface 13.Grooves having inclined bottom walls are provided on the base plate orflange 9.

In use, the connecting member B is first positioned. Thereupon, thecomplementary rails are connected thereto. During the connecting action,the rails are moved to position over theconnecting member where theteeth 4 can move or slide into the notches intermediate teeth 11. Whenthe teeth slide into the notches, the beveled or inclined walls 5 rideon the beveled or inclined walls 12, whereby the teeth will slide easilyinto inter-engagement. When the teeth have become thus engaged, thesurfaces 7 will rest or bear upon the surface 13 and the base plateorfiange 9 will be received in the cut out portions 6 of the rails. Byreason of the inclination of walls 8 and 14:, the connecting member andsections will be prevented from moving or being jarred lat erally.

As merely the preferred form of the in vention has been shown anddescribed, such changes as fall within the spirit and scope of theappended claims are reserved.

Having thus described our said invention,

what we claim as new and desire to secure by Letters Patent, is i 1. Incombination with rail members, a rail connecting member, an enlargementformed upon the extremity of each of the said rail members, eachenlargement being cut away at the base thereof, teeth formed integrallywith the said rail member adapted to depend into the said cut awayportion, theteeth of one rail member extending op positely to the teethof the other, a rib formed upon" the said connecting member disposed tolit the said, cut away portion, inclined surfaces formed upon theconnecting member adapted to form seats for inclined faces formed uponthe said enlargement, teeth formed integrally with the connectingmember, the teeth upon one end thereof being inclined oppositely to theteeth upon the other, the teeth upon each end adapted to mesh into thecorresponding teethformed upon the rail member to fasten the saidmembers together, as and for the pur pose set forth.

2. In combination with rail members, a rail connecting member,enlargements formed upon the extremities of the said rail members, thesaid enlargements being cut away at the base thereof, a longitudinallyextending recess open to the said cut away portion, teeth formedintegrally with the said rail member adapted to depend into the saidrecess, a longitudinally extending rib formed integrally with the saidconnecting member, inclined surfaces formed upon the 20 said connectingmember adapted to form seats for inclined faces formed upon the saidenlargement a fiat bearing surface formed centrally upon the said rib,teeth formed integrally with the said rib upon each side 25 of the saidfiat bearing surface, the teeth upon one side of the said surface beinginclined oppositely to the teeth upon the other, the teeth upon eachside adapted to mesh into the corresponding teeth formed upon 30 Copiesof this patent may be obtained for five cents each, by addressing theCommissioner of Patents, Washington, D. G.
